📚 Etymology▼

Comes from 'supuesto', the past participle of the Spanish verb 'suponer' (to suppose). This verb itself comes from the Latin 'supponere', which meant 'to place under' or 'to substitute'. Over time, the idea of placing one idea under another evolved into the meaning of 'assuming' or 'supposing' something to be true.

First recorded: 13th century

Frequently Asked Questions

What's the difference between 'por supuesto' and 'claro'?

They are very similar and often interchangeable for 'of course'. 'Claro' can feel a bit more like 'right' or 'clear', while 'por supuesto' is a strong 'absolutely' or 'naturally'. You can't go wrong using either to agree with someone.

Is 'supuesto' related to 'presupuesto' (budget)?

Yes, they are related! A 'presupuesto' (budget) is a 'pre-supposition'—an assumption you make beforehand about how much money you will need or spend. Both words come from the same idea of 'supposing'.

Can I use 'supuesto' to start a sentence?

Yes, but it's usually part of a longer phrase. You can say 'Por supuesto, tienes razón' ('Of course, you're right') or 'Supuesto que sí' (a more emphatic 'Of course'). However, simply starting with 'Supuesto...' on its own is not common.
